Abstract

A method and system for CDMA mobile radio communication by which the autonomous decentralized control of radio channel assignment, synchronous control for the smooth establishment/switching, and VOX control for increasing the capacity can be realized. In either the base station or the mobile station, one of prescribed short spreading codes is selected, and the frequency band of an information sequence to be transmitted is spread by using the selected short spreading code and prescribed long spreading codes and then transmitted. In the other station, the received information sequence is reproduced by compressing the spread frequency band, using the selected short spreading code and prescribed long diffusion codes. Before handing over the information sequence, information to be handed over from a base station to a mobile station and information to be handed over from the mobile station to another base station are spread using both long and short spreading codes. The informations received by the base and mobile stations are combined synchronously. In at least either of the base and mobile stations, the VOX control of the transmission frames transmitted through a radio channel is performed. The offsets with respect to the transmission timings are assigned to the respective channels at random and transmitted.
